Basics
What size bike do I need?
Below is the recommended sizing for the Transition Regulator CX E70 2027 2025 Here you should measure your height with your shoes off.
Small
153cm – 170cm
Medium
165cm – 183cm
Large
175cm – 190cm
Xlarge
185cm – 200cm
Please Note: Many bike brands’ size guides overlap slightly. This is because small adjustments like seat position can accommodate riders who fall between sizes. When you’re in this overlap zone, the choice comes down to preference: a larger size for a more stretched-out ride, or a smaller size for a more compact feel.
At MTB Monster, we help customers on a daily basis choose the right size bike for their needs. We consider your measurements, riding style, and past bikes to help recommend the best size. If you’re in doubt at all or want to just confirm your thoughts please
contact us
and we would be glad to help.
What is Frame Protection and is it worth fitting it to the Regulator?
Frame Protection in our opinion is money well spent. Your bike is an expensive investment and frame protection helps to protect your paintwork from scratches, scuffs and chips to keep your bike looking spotless for years to come. In essence, frame protection is a custom cut, self-healing frame protection film made from Lotus Pro 10 – 10.3mil thick TPU film (or similar) designed specifically for mountain bikes and electric bikes. It features a ceramic-embedded hydrophobic top coat that effectively repels water, mud, and dirt, making post-ride cleanups faster and easier. Kits are available in both gloss and matte finishes and unless specifically requested we would fit the kit to match the finish of your paintwork. Some bikes have a mixture of matte and gloss paintwork and in most cases mixed finish kits are available. The material of a frame protection kit will act as an extra layer of clear coat and can make the finish of raw carbon more prominent due to the way that the light refracts. Similarly, fitting a matte finish kit can produce a more satin finish and mean that the kit is slightly more visible than when it is installed in a gloss finish.
Currently there are 3 options available
1. Supply and fit.
Our trained and experienced mechanics can install frame protection kits here so that your Regulator CX XT 2025 arrives fully protected and ready to ride. We recommend a 48 hour curing period to ensure that the film adheres properly to the frame, so your order will take a little longer to arrive — but it will be well worth the wait.
2. Supply Only.
If you choose to install the kit yourself, we’ll provide you with the kit, instructions, and a squeegee. Just select “Supply Only” and your kit will arrive with your bike — there is no delay to dispatch with this option. There are many informative videos online to guide you through installation. We would advise watching these in advance to see if you feel confident to fit the kit. Patience is a must when it comes to installation.
3. N/A.
Choose this option if you would prefer not to have frame protection fitting.
Please note: If no frame protection kit has been designed for the bike yet, no option other than N/A will appear. However, there is a very good chance we may still be able to get one designed or custom templated to fit. If this is of interest, please
contact us
here and we can look into it as soon as possible.

What is tubeless setup and can the Regulator be set up tubeless?
So, what’s a tubeless setup? Traditionally, inner tubes are inflated with air to create a cushion between the rim and tyre. In contrast, a tubeless setup ditches the inner tube and relies on a specially designed rim with an airtight seal. A self-sealing liquid is added directly inside the tire, and air is pumped through a special valve to inflate the tyre. This allows riders to run lower pressures for better grip and comfort, and the sealant can plug small punctures on the fly, reducing flats.
However, it’s important to note that bike manufacturers send their bikes to us in varying degrees of readiness to be set up tubeless. For example, some may supply suitable tubeless-ready tyres, but not the valves or sealant, while others arrive with everything you need. So here at MTB Monster we’ve checked and answered the following two questions;
Can the Transition Regulator CX E70 2027 be set up tubeless? Yes, this bike can be set up tubeless.
What option do I need to select, if I want the bike setting up tubeless before I receive it?Your bike is set up tubeless from the factory. If you’d prefer inner tubes instead, please let us know.
What equipment & info will the bike arrive with?
In the box, you’ll find your owner’s manuals with your Pre-Delivery Inspection Checklist, signed off by our Cytec qualified mechanic. This details all the checks that have been completed along with an ‘Important Information’ sheet explaining the advised pre-ride checks to be carried out to ensure the bike is safe to ride and that it will perform at its best. We advise keeping this document safe in case it is required in the future.
We also include a bike battery charger with a UK specific plug for the Transition Regulator CX E70 2027, the relevant allen keys to assemble your bike (normally 2), brake separators to keep your brakes apart whilst the wheel is out of the bike along with any manufacturers manuals, and any extras the brand has included. Some manuals are now only accessible online and paper copies are not included, if you require any assistance accessing manuals for your new purchase please get in touch.
It is worth being aware that bikes are rarely supplied with pedals included. This information will be detailed in the specification of the model you choose. If your bike is not supplied with pedals and you don’t currently have any suitable ones, we have a great range on offer here
Any promotional freebies such as an MTB Monster mudguard will also be included in your box.
If you feel you are missing any parts of your kit please
contact us
within 24 hours of delivery so that we can help.
Is it possible to see the Regulator in your showroom & is it possible to have a test ride or demo it?
Showroom
Viewing
While we showcase Transition e-bikes and often have the Regulator model on display, we can’t guarantee the exact bike you see online will be ready to view at any given time. This is because bikes might be recently sold, boxed in our warehouse, or still with the manufacturer. To ensure you see a specific bike you’re interested in, please
contact us
before your visit & we’ll do our best to have it available on the day of your visit or make alternative arrangements.
Can I demo & test ride the Transition Regulator CX E70 2027?
We stock a wide variety of electric mountain bikes (eMTBs) for you to test ride at our
showroom
in the North-West of England. Our selection features various sizes, brands, and motor options, allowing you to compare different types of eMTBs – from standard models to lightweight ebike options. We offer test rides ranging from quick car park loops to more in-depth demos, tailoring the experience to your needs.
To see whether the Transition Regulator CX E70 2027 is available to view or try out, please

& we do our best to arrange something with you prior to your visit.
What type of bike is the Regulator and what is it designed for?
The Transition Regulator CX E70 2027 is classed as a enduro bike designed for conquering challenging terrain that mixes technical climbs with rough, steep descents. Its superb balance of weight and downhill capability making it a firm favourite with more aggressive riders. .
What type of terrain is the Regulator ideally suited towards?
Like all Electric mountain bikes they can be used on gravel paths and forest tracks, but the bike will really excels on downhill sections with features like drops, jumps, rock gardens, and loose scree. Whether you’re racing enduro, hitting the bike park, or tackling a black run, an enduro MTB can handle it all. /p>
Can the Transition Regulator CX E70 2027 get wet and muddy?
Absolutely! All ebike systems are designed from the ground up to live in the harshest conditions of mountain biking. You don’t need to be concerned about riding the bike through a British winter, or in fact a British summer. In fact, these bikes are fully rainproof, ready to tackle endless puddles and wet, muddy trails without hesitation. The system utilises automotive grade electric ports and specifically designed covers to protect the system while providing the best weather protection so that you don’t need to worry about riding in UK conditions. .
While the Transition Regulator CX E70 2027 is designed with waterproof weather protection at the forefront, we would advise to avoid situations which would submerge the bike for any duration of time and against pressure washing the bike…just like we wouldn’t advise for a regular bike.
How should you clean & maintain the Transition Regulator CX E70 2027?
Cleaning an ebike is no different to cleaning a regular bike, a brush and hose pressure method is the best way. We advise against using a pressure washer as this often drives water behind seals, washing grease from bearings and also forcing water into electrical components. It’s also best to avoid any harsh chemicals or abrasive cleaners as these can damage the finish of the frame and components. MTB Monster offer a range of
recommended cleaning products
that are designed for ebikes and non-ebikes.
Can you tell me about the Transition brand?
Rider owned since the start, Transition has always made a commitment to best serve riders with the bikes that they want to ride rather than the need to slot into a predefined category. Where fun is the aim, Transition’s answer is GiddyUp, a suspension design designed to behave intuitively. Transition also offers Speed Balanced Geometry, SBG, which ensures low speed agility, front wheel traction and rider weight balance..
Our staff ride Transition’s so if you want to know any details first hand from an owner, let us know and we will be happy to help.
I’m new to riding, what essential bits of kit do I need to get going?
Getting started can seem daunting but there’s only a couple of kit items that are essential for a safe and self-sufficient bike ride.
Above all else, a
helmet
is the most essential piece of kit. It dramatically increases safety when you’re out riding. To put this in context, if you visited a UK mountain bike trail centre, you’d be hard-pressed to find anyone riding without one. Rider protection wise, this can be extended to
gloves
,
knee pads
and
elbow pads
depending on type the terrain that you are looking to tackle.
We would always recommend riding with a
spare inner tube
,
tyre levers
and
pump
. Most riders have a story about the time they got caught out with a puncture, usually in horrible weather and miles from the endpoint of the ride, learn from our mistakes 🙂 Additionally, a number of mechanicals can be resolved on the trail with a handy
multi-tool
, these usually contain a range of hex keys, torx keys and occasionally a chain breaker to help you get to the end of the ride and into a fully equipped workshop.
For any additional advice, feel free to
contact us
and we’ll be more than happy to help.
Where can I ride the Transition Regulator CX E70 2027?
In the UK, you can ride an ebike anywhere that you would ride a normal pedal bike.
There are no restrictions in trail centres to prevent you from using an ebike anywhere that you would use a regular bike without assistance.
Local to store, we have Longridge Fell, Gisburn Forest and also Darwen Moors & Rivington. Within around an hours drive, you have the Lake District, North Wales, Yorkshire Dales & the Peak District offering a wealth of amazing riding opportunities. If you’re ever looking for a route nearby, let us know and we can point out some highlights.
Throughout the wider UK, there are over 20,000 miles of bridleway and over 16,000 miles of national cycle network. Additionally, canal paths, forest roads and cycle lanes all offer a great network to connect your ride and minimise the amount of time that you need to ride on busy roads. A good starting part to find some fun mountain bike specific routes that cater for all abilities are trail centres. These are designed specifically for mountain bikes and are often located through the UK’s many forest areas. Some great websites to check out as a starting point are; mbwales.com (Wales), dmbins.com (Scotland), forestryengland.uk/cycling (England) and mountainbikeni.com (Northern Ireland). One of our personal favourite riding spots at MTB Monster, is within the Tweed Valley area in Scotland, where the design of the tracks are simply world class and cater for all abilities.

If you select the technical tab on any product page you will see ‘pedals’ as a one of the items and here it will tell you if they come as standard from the manufacturer. By reducing the number of components included with a new bike, manufacturers can minimise waste and packaging. With so many different types of pedal available it’s unlikely that anything manufacturers include will suit everyone.

here
and of course if you are unsure please get in touch for some friendly advice.

Are electric bikes legal? How fast can the Transition Regulator CX E70 2027 go?
The electric bikes that we sell at MTB Monster are completely legal to ride in the UK, both on-road and off-road. The maximum speed that an ebike can be assisted to in the UK is 15.5mph (25kph). It is easily possible to ride an ebike faster than 15.5mph but the motor will not offer any assistance beyond this point. The Transition Regulator CX E70 2027 is set at the maximum level of assistance permitted in the UK.
Do I need a license to ride the Transition Regulator CX E70 2027 in the UK?
Pedal bikes with electric support up to 15.5mph (25 km/h) are regarded as equivalent to bicycles by law and therefore, do not require vehicle insurance, a registration plate or a driving license
Can I add upgrades to the bike?
Yes most upgrades on the Transition Regulator CX E70 2027 are fine, if you fancy changing the brakes, adding some blingy new grips, or maybe a change of fork, you’re welcome to make these changes. However, just make sure they are both suitable & compatible with the bike.
Please note with E-bikes:
Changes in gearing or wheel size will need to be reflected in the motor programming as this can affect speed ratings, and this is where it starts to get tricky as it will require the brand’s authorisation. Typically changing anything to do with the motor system of an electric bike is not recommended unless advised otherwise by the bike/motor manufacturer.
Electric / Battery
How should I store the bike?
How you store the Transition Regulator CX E70 2027 is pivotal for maintaining its condition and ensuring the e-bike is ready to go when you are. Ebike’s should be stored clean and dry in a cool environment between 10 to 20°C, with the battery level between 30-60%.
If a battery is ever stored separate to your bike, again make sure it’s stored in an area without significant temperature fluctuations. Somewhere that endures extreme temperature changes – such as an outdoor shed for example.
What is the battery lifespan on a Transition Regulator CX E70 2027?
Batteries are highly complex components and are designed to offer a long service life. The service life of the battery is influenced by several factors such as the amount of charge cycles, intensity of usage, charging practice and storage temperatures. That being said, under typical use of going out riding a few times a week, you should expect to get a couple of years of riding without any problems, as that has been our experience for 99% of the ebikes we have sold to date.
Also it’s worth bearing in mind, we still have plenty of customers riding bikes purchased over 5 years ago with the original battery, and very rarely do we have customers complain about battery issues. And for peace of mind, if anything was to happen, the batteries themselves are covered by warranty for the first 2 years of use.
Are Lithium-Ion batteries safe?
Lithium-Ion batteries are, provided certain precautions are met, are safe.
The high-quality lithium-ion batteries fitted to our range of e-bikes are equipped with a Battery Management System (BMS) which is continuously acting to detect potential sources of error and protects the cells from overload, undervoltage, overheating and short-circuiting.
According to the Bicycle Association there is a very low risk from un-modified legal Electric Assist Pedal Cycles (EAPCs – street-legal eBikes) if bought complete with their approved batteries and chargers, from reputable brands, sold by reputable retailers, and handled according to the manufacturer’s’ instructions.
All of our bike brands we sell, and the electrical componentry they use on their e-bikes, are fully regulated and adhere to the highest standards. It’s also worth noting, that they are simply worlds apart in terms of safety, when compared to cheap unregulated imported e-bikes that you would find on any online auction sites.
Is the internal battery removable on the Transition Regulator CX E70 2027?
It’s recommended that only a qualified mechanic removes the battery from this bike, as the motor needs to be dropped out in order to access and remove the battery (via specialists tools). Often EMTB designers prefer this over a easily removable battery as it allows them to both reduce weight and improve the performance of the bike.

– Mountain e-Bike.

What is a range extender and can you add one to the Transition Regulator CX E70 2027?
A range extender is an additional power bank that can be connected to the bike for longer rides which the main battery capacity wouldn’t satisfy. The PowerMore 250 is compatible with the Regulator CX.
If we have the range extender in stock, we will add a purchase link on the technical tab of the product page (next to range extender) to add to your shopping cart if required.
Does the bike arrive fully charged and ready to go?
For fire safety, couriers have restrictions that prevent the shipping of electric bikes with more than 30% charge. This will be more than enough to take your new bike for a quick spin but the bike will require a full charge prior to your first proper ride
How to charge the battery on the Transition Regulator CX E70 2027?
The battery is integrated in the downtube and is charged through the port on the frame.
The best practice is to firstly connect the charger to the charger port then plug into the wall socket. This way the charger will automatically switch on and start charging your battery when connected to the wall socket and switch off supply once the bike is fully charged therefore preventing overcharging the battery. As the battery is charged the display (if fitted) will also be charged up at the same time.
How long does it take to charge the battery?
Bosch advise 6.9 hours for a full charge on a 800wh battery with a 4A charger and 2.6 hours and for a 50% charge. Whereas the 600wh battery is advised to take just over 5 hours for a full charge and 2 hours for a 50% charge.
How is the motor protected ?
The motor on the Transition Regulator CX E70 2027 is protected by a plastic guard which will shield the motor from the worst of the trail conditions and will act as a sacrificial part to protect the motor from impact should you require it.
